Well, being a Klingon definitely DOES give you an excuse to come armed to your teeth even to Her Majesty's, Queen of Britain, audience. But other than that... it's definitely not a practice of Starfleet officers to buzz around with weapons.
Plus Klingons are much more fun than the pyjama boys (:}}

Hear! Sons of Kahless
Hear! Daughters too.
The blood of battle washes clean.
The Warrior brave and true.
We fight, we love, and then we kill.
Our lives burn short and bright.
Then we die with honor and join our
fathers in the Black Fleet where we
battle forever, battling on through
the Eternal fight.
